Xtreme – M90U-80 – 40000 – 40 kVA – Three Phase Online UPS

Xtreme Power M90U-80 Modular UPS — Scalable 40 kVA, 208/120V Three-Phase

The Xtreme Power M90U-80 is a modular three-phase UPS that delivers
scalable, online double-conversion protection for mission-critical IT and industrial applications.
Operating at 208/120VAC three-phase with unity power factor (1.0 PF) output, the M90U-80 combines
hot-swappable power and battery modules with an ultra-compact footprint to provide exceptional reliability,
serviceability, and space efficiency in today’s high-density environments.

Available in configurations up to 80 kVA, the M90U-80 uses modular 20 kW power modules
to scale capacity or add N+1 redundancy as your load grows. A large 10″ color touchscreen provides advanced
system monitoring, while flexible dual or single utility input options and a front-mounted maintenance bypass
deliver some of the highest availability and ease of service in its class.
